1988～1992年连续5年对蚊媒进行纵向监测观察，各年致倦库蚊的自然感染率分别为0．11％、0．03％、0．03％、0．01％和0．01％，呈逐年下降的趋势，且仅在前3年有发现感染期幼虫；而中华按蚊则未发现自然感染蚊只。每年计算致倦库蚊的年传播潜势分别为350．48、186．92、186．92、0和0，均未达到起传播作用的量。横向监测，1992～1996年在原流行区40个县市119个乡镇的225个管理区共解剖致倦库蚊117404只，中华按蚊1256只，均未发现人体丝虫感染。结果表明广东省丝虫病的传播已完全被阻断。
The mosquito media were monitored vertically for 5 years from 1988 to 1992. The natural infection rates of Culex quinquefasciatus in each year were 0.11%, 0.03%, 0.03%, 0.01% and 0.01 %, Showing a declining trend year by year, and only infected larvae were found in the first three years. However, mosquitoes infected with Anopheles sinensis were not found. Annual annual transmission potential of Culex quinquefasciatus were calculated as 350.48, 186.92, 186.92, 0 and 0, respectively, and did not reach the level of transmission. Lateral monitoring: from 1992 to 1996, 117,404 Culex pipiens pallens and 1256 Anopheles sinensis were dissected in 225 administrative areas of 119 townships in 40 counties and cities in the original endemic areas. None of the human filarial infections were found. The results showed that the transmission of filariasis in Guangdong Province has been completely blocked.
